THE ASYMPTOTIC BEHAVIOUR OF THE EIGENVALUES DIFFERENTIAL EQUATIONS WITH A TURNING POINT

This paper deals with the boundary value problems for secondorder differential equation on the half-line having a turning point. Using of the asymptotic estimates for a special fundamental system of solutions of the differential equation the half-line, we study the asymptotic distribution for eigenvalues.
